摘要
小井眼钻井特定的井眼结构与钻井工艺条件决定了其环空水力学与常规井眼有较大区别,因此其钻井液技术也具有一定的特殊性。在选择小井眼钻井液的合适流变模式的基础上,分析了小井眼窄环空间隙对钻井液技术的特殊要求,提出了实现小井眼钻井的钻井液技术参数和措施;并且通过对塔河油田侧钻小井眼TK209CH水平井的钻井实践,进一步论证了小井眼钻井中钻井液参数合理选择的必要性。
On the conditions of hole structure and drilling technology of slim hole drilling,the annular hydraulics is much different than the normal holes.Consequently,the feasible flow structure of drilling fluid is critical to slim hole drilling,and the drilling fluid technology is developed to optimize the drilling fluid performances that is successfully applied in well TK209CH.
